Traditional is right up my alley! For the chandelier, I prefer clear crystals since they reflect light beautifully and really open up a space. For a dining room table and chairs, here are some suggestions:

This is a suggestion without knowing the size of your dining room and if you prefer light or dark wood. I always look for comfortable chairs, for myself and my mom and MIL who are in their 80's.

My daughter purchased a gorgeous dining room set from Haverty's when she purchased her townhouse in Virginia.

As for rugs, what colors do you prefer and are you keeping the same dining room colors?

I happen to like what I can see of your rug.

I can tell you that Swarovski crystals sparkle like no other! I have been using them in my jewelry designs for almost 18 years.

I like dark furniture and would like a table that seats 8-10. I like upholstered chairs.

That helps a lot! I like the same for my dining room too. Here are some more dining room tables and chairs ideas:

I bought a dark table separate from the chairs. Upholstered chairs are tricky to find. Why? Because the dimensions state the seat height from the top of the cushion. Most are made with flimsy foam and you SINK when sitting. Allow me to spare you precious time & effort.... We shopped everywhere (RH, EA, C&B, WE, CPWM, M, MB, AF, B! MF). At last, we found the perfect one: PB Hayes chair!!!

The concave back is sooooo comfortable. Choose your fabric.

This Table extends to 101 inches. How big do you need?

Right now the table is 138" but I think it looks best at 120"

With such a long table, choose a rectangular chandelier

I like the rectangular chandelier!

The room will be stunning!

I noticed that most of the rooms with upholstered chairs have wood floors. Since I have tiles do you think I should get chairs with some wood?

Upholstered chairs have wood legs.

Put an area rug under chairs and table

remove the sconces

new wall art. no mirrors

When you replace the rug, if you can't fit one that is 4' longer and wider than the table, then skip the rug. The one in the photo in your original post is too short. No rug looks better than one that's too small.

Picture shows the table fully extended with three leaves (new buyer wanted to see it that way). Normally, I have it with just two leaves. I'll get rid of the mirror/sconces and wall art. Any suggestions for new wall art? Is the rug outdated, should I replace it too?

Re: wall art & rug

Do you have/ want a fluid color scheme or decor theme, while keeping with the traditional style? What are the colors in the rooms -near to the dining room? (More pics are always helpful.)

You've planned a dark table and light upholstered chairs.....

Do you want color or would you like neutral tones?

Neutral rooms are not void of color or interest when greenery is added.

Another rectangular chandelier:

Also.... Did you like either chandelier from post above (Pottery Barn's Bella or West Elm's capiz shell)?

Thanks DK - The rest of the house is very neutral, mostly brown and beige with little pops of red. I would like to add some color. The rug has a lot of blue and I would like to (am trying to) add some blue and green in the rest of the house to lighten things up. The kitchen counter has a lot of rust in it. I will post some pictures later. I do like the rectangular light, but those two didn't really grab me.

"Brown, beige with little pops of red... add some blue and green."

What shade of blue!

What is the condition of your current blue/gray rug?

Does it need replacing?

When you say add blue.... Do you want the same blue/gray or a different shade or. brighter hue? (cobalt, teal, turquoise, aqua/sea blue, baby blue, bright blue sky blue)?

The blue/gray rug in the dining room is in pretty good shape. The rug in the family room is more brown but I don't want to replace that as that was a $15K rug. Looking around, everything just look so neutral. I want to add color and I think adding blue and/or green would brighten things up without clashing too much. But I don't know what color blue or what color green. I thought maybe turquoise blue, and maybe apple green?? I'm at a loss. For now, I want to focus on the dining room. I was thinking of painting the wall above the chair rail a warm gray and painting the bottom white. Or should I paint everything one color as it is now?

Like these? Pretty!

Love the table/chairs in Royal York Reno.....where would I find that?
